Zusammenfassung

In the field of music processing, there are many related issues commonly subsumed under the
notion of source separation. The goal of this talk is to present various approaches for decomposing a given
music signal into semantically meaningful components. In these approaches, additional information, either in
the form of specific acoustic properties of the components or in the form of additional score information, is
exploited. Rather than giving a comprehensive overview of source separation and its many related tasks, we
considered in this talk three specific scenarios along with some key techniques that are widely used in music
processing and beyond. First, we look at the task of harmonic-percussive separation. Building on a classic
and well-known approach, we extend the decomposition with a third residual component that captures all
sounds which are neither of clear harmonic nor of clear percussive nature. Second, we introduce a cascaded
audio decomposition approach with the aim to isolate the singing voice. Third, we present an approach to
audio mosaicing which is inspired by non-negative matrix factorization (NMF).

Vortragender

Meinard Müller studied mathematics (Diplom) and computer science (Ph.D.) at the University of
Bonn, Germany. In 2002/2003, he conducted postdoctoral research in combinatorics at the Mathematical
Department of Keio University, Japan. In 2007, he finished his Habilitation at Bonn University in the field of
multimedia retrieval. From 2007 to 2012, he was a member of the Saarland University and the Max-Planck
Institut für Informatik leading the research group Multimedia Information Retrieval and Music Processing
within the Cluster of Excellence on Multimodal Computing and Interaction. Since September 2012, Meinard
Müller holds a professorship for Semantic Audio Processing at the International Audio Laboratories Erlangen,
which is a joint institution of the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the Fraunhofer-
Institut für Integrierte Schaltungen IIS. His recent research interests include music processing, music
information retrieval, audio signal processing, and motion processing. Meinard Müller has been a member of
the IEEE Audio and Acoustic Signal Processing Technical Committee from 2010 to 2105 and is a member of
the Board of Directors of the International Society for Music Information Retrieval (ISMIR) since 2009. He has
co-authored more than 100 peer-reviewed scientific papers, wrote a monograph titled Information Retrieval for
Music and Motion (Springer, 2007) as well as a textbook titled Fundamentals of Music Processing (Springer,
2015, www.music-processing.de).
